Machined from brass and finished with zinc plating per ASTM B633, QQ-B-626 Comp 22 Type 1, this spacer measures 0.5 inches overall length with a 0.1875-inch outside diameter and a 0.089-inch inside diameter. It accepts a number 2 screw size and provides consistent, corrosion-resistant separation in electronics assemblies. Licensed electricians, electronics technicians, and panel builders use these spacers during board mounting and chassis assembly work.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for residential and light commercial circuit board installations where a compact, round standoff is required. Typical applications include control board mounting in HVAC equipment, electrical panel assemblies, and industrial enclosures where a number 2 fastener and a 0.5-inch standoff height are specified. The zinc finish provides added corrosion resistance in environments where moisture exposure is a concern. Sold individually with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded body accepts number 2 screw size for straightforward board mounting\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc plating meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards\u003c\/li\u003e\n  \u003cli\u003e0.5-inch overall length with tight length tolerance of -0.005 to 0.005 inches for consistent standoff height\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches ensures reliable screw fit\u003c\/li\u003e\n  \u003cli\u003eRound body shape compatible with standard PCB mounting hole layouts\u003c\/li\u003e\n  \u003cli\u003eCompact 0.1875-inch outside diameter suits dense board layouts with limited clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit spacer for circuit board assemblies requiring a number 2 screw, female unthreaded round standoff with a 0.5-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed electricians or qualified electronics technicians. De-energize all circuits and discharge any capacitors before handling circuit boards or installing standoffs. Use a number 2 fastener matched to the board specification and do not overtighten, as brass spacers can deform under excessive torque. Follow all applicable NEC guidelines when installing control boards within electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B633, QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: Number 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.089 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELECTRO HARDWARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S309M01F21C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51747032269106,"sku":"S309M01F21C","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_bd4d25d1-9eb5-4dd0-9911-52957aa2c5b8.jpg?v=1788875467","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s309m01f21c-circuit-board-spacer-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
